Hi modz9636--I think you can probably cook it for about 2 hours and check to see how far it's progressed, based on how easily the meat flakes and gives to your fork...I've found that irregardless of how much meat you're actually cooking, the slow-cook time actually makes a big difference in terms of getting that pulled pork texture just right. (I tend to make more when I'm making these buns because I've never suffered for excess of leftovers, but you can obviously cut down to as much as you like!)
